In this competition, you are provided with a training set containing time-frequency data from two gravitational-wave interferometers (LIGO Hanford & LIGO Livingston). Each data sample contains either real or simulated noise and possibly a simulated continuous gravitational-wave signal (CW). The task is to identify when a signal is present in the data (target=1).

Each sample is comprised of a set of Short-time Fourier Transforms (SFTs) and corresponding GPS time stamps for each interferometer. The SFTs are not always contiguous in time, since the interferometers are not continuously online.

The simulated signals are present throughout the entire duration of the set of SFTs in both detectors. The signals are characterised by the location and orientation of the hypothetical astrophysical source as well as two intrinsic parameters: frequency and spin-down. In total there are eight parameters which have all been randomised. These are not provided as part of the data. The typical amplitudes of the resulting signals are one or two orders of magnitude lower than the amplitude of the detector noise.

Further resources regarding the specifics of the data format can be found in [this pinned discussion](https://www.kaggle.com/competitions/g2net-detecting-continuous-gravitational-waves/discussion/347052).

## Files

*   **[train/|test/]** - folders containing the training and test files; **Note:** a small example set of training data has been provided, although it is expected that competitors will need to generate additional data for training as described [here](https://www.kaggle.com/competitions/g2net-detecting-continuous-gravitational-waves/discussion/347052).
*   **train_labels.csv** - a file containing the `target` labels; `1` if the data contains the presence of a gravitational wave,  `0` otherwise. (Please note the presence of a small number of files labeled `-1`. Physicists are currently unable to determine the status of these files.)
*   **sample_submission.csv** - a sample submission file in the correct format; your task is, for each file in the `test/` folder, to predict the probability between `[0, 1]` of it it containing a continuous gravitational wave signal.
